TIBPAL22V10-7CNT

Overview

The TIBPAL22V10-7CNT is a high-performance IMPACT-X programmable array logic circuit manufactured by Texas Instruments. It features up to 22 inputs and 10 outputs with an average of 12 product terms per output. The device utilizes Advanced Low-Power Schottky technology and titanium-tungsten fuses, achieving a maximum propagation delay of 7.5 ns and an external feedback frequency of 80 MHz. Each output is individually configurable for registered or combinational operation, polarity, and enable control. It operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range of 0°C to 75°C.

Feature Summary

• High-speed performance with 7.5 ns max propagation delay and 80 MHz max external feedback frequency
• Variable product term distribution (8 to 16 terms per output) for complex function implementation
• User-programmable output logic macrocells supporting registered/combinational modes and polarity selection
• TTL-level preload capability for improved testability and power-up clear on registered outputs

Applications

• Custom LSI functions requiring complexities of 500 to 800 equivalent gates
• State-machine initialization and logical verification during product testing
• Systems requiring synchronous set and asynchronous reset capabilities

Procurement Notes

Verify the specific package type required, as the device is available in both Plastic DIP (NT) and Plastic J-Leaded Chip Carrier (FN). Confirm that the application environment remains within the specified 0°C to 75°C operating temperature range. Ensure the design accounts for thermal management if operating at high frequencies with multiple simultaneous output switches.

Selection Notes

Select this component when a second-generation PLD architecture with variable product term distribution is needed. Choose the NT package for through-hole mounting or the FN package for surface-mount applications. Ensure the design utilizes the 5 V nominal supply voltage and respects the absolute maximum ratings for input voltages and short-circuit durations.

Part Context

This device belongs to the TIBPAL22V10 series of IMPACT-X programmable array logic circuits. It is functionally equivalent to other PAL-type devices but offers specific timing characteristics defined by the -7 suffix. The series provides a reliable substitute for conventional TTL logic using proven titanium-tungsten fuse technology.

Replacement Considerations

The datasheet notes functional equivalency to AMD AMPAL22V10 and AMPAL22V10AD devices. Verify pinout compatibility and electrical specifications before substituting.
